FIELD: power industry.
SUBSTANCE: heat generator includes a housing with heated air inlet and outlet holes and nozzle of fuel combustion device, tubular flue gas channel arranged inside the housing and made in the form of heat exchange tubes equipped on the outside with profiled screens and attached to each other by caps, and convective heat exchanger with installed heat exchange elements, gas distributing heads and a stack; at that, convective heat exchanger is two-pass; flue gas duct, the first and the second pass of convective heat exchanger is located in series along heat generator housing; upper distribution head of the first pass is connected to the last heat exchange tube in the direction of flue gases; separately located upper distribution head of the second pass is connected to the stack; lower distribution head which is common for both passes is provided with a condensate discharge nozzle, and nozzle of fuel combustion device, the first heat exchange tube in flue gas direction and a return bend adjacent to it are provided with flanges.
EFFECT: improving heat engineering and hydrodynamic properties, increasing efficiency coefficient of heat generator.
